This report describes the development by Radiation of X-band solid-state frequency converters as part of a transportable terminal for use with the military DSCS-2 communications satellite. This equipment was developed under contract with the U.S. Army Satellite Communications Agency. The converters are fully self-contained in two 3-1/2 inch rack-mounting drawers. They provide the capability for translating a signal anywhere in the 7.25-7.75 GHz receive band down to 70 MHz and, similarly, of translating a 70 MHz signal up to the 7.9-8.4 GHz transmit band. Hybrid microwave integrated circuit (HMIC) techniques were employed extensively in the terminal converters to aid in minimizing size and weight and in enhancing reproducibility. The actual construction is a blend of microstrip and stripline distributed circuits and miniaturized lumped-element circuits.
